If you use my answer, please remember to "measure twice, cut once"; that is, check this on paper before cutting...

Since 56" / 4" = 14, you may need only 14 lines of lumber (provided that the planks are a true 4").

Also, I am assuming that there is no loss when you make a cut (or the loss will be covered by quarter rounds at the ends).

You could have lines (in any order)

19-19-19          17-17-23          13-19-25         16-17-24

17-18-22          17-11-29          19-16-22         12-12-33

17-14-26          7-19-31            17-20-20

18-10-19          17-5-35            14-24-19

Need 8 boards cut 19-17          1 cut 18-18          2 cut 22 -14         1 cut 26-10

                    1 cut 23-13         1 cut 25-11          1 cut 29-7            1 cut 31-5

                    1 cut 35-1           2 cut 20-16          2 cut 24-12          1 cut 33-3

No wasted boards, only 4" not used.

I don't know of any mathematical formula; try these (before cutting)!
